1、Research and Design of Packet Filtering based on NDIS Intermediate Driver
基于NDIS中間層的包過濾的研究與設(shè)計

2、After the rules are built and chains are in place, the real work of packet filtering starts.
建立規(guī)則并將鏈放在適當的位置之后，就可以開始進行真正的信息包過濾工作了。

3、Figure 1 graphically illustrates this packet filtering process.
圖1用圖形說明了這個信息包過濾過程。

4、These rules are stored in special-purpose packet filtering tables integrated in the Linux kernel.
這些規(guī)則存儲在專用的信息包過濾表中，而這些表集成在Linux內(nèi)核中。
